Embedded Technology
Content:
A key technology enabling fast-paced embedded media processing developments is the high-performance, low-power, small-footprint convergent processor, a specialized device that combines the real-time control of a traditional microcontroller with the signal processing power of a DSP. This practical guide is your one-stop shop for understanding how to implement this cutting-edge technology.You will learn how to:* Choose the proper processor for an application.* Architect your system to avoid problems at the outset.* Manage your data flows and memory accesses so that they line
